BUGGY-EVENER CLEVIS.

Specification of Letters Patent.

Patented J an. 30, 1912.

To all whom, t may concern.'

Be it known that we, OLE A. FLADBY an'd JOHN B. FLADBY,' of Rutland,Sargent county, North Dakota, have invented certain new and usefulImprovements in Buggy-Evener Clevises, of which the following is aspecication.

Our invention relates to safety clevises for eveners and swingle trees.

The object of the invention is to provide a clevis capable of pivotallyconnecting a swingle tree with an evener without the use of screws orbolts extending into or through said swingle tree, thereby avoiding theweakening of the wood of the swingle tree at the point of greateststrain.

The invention consists generally in the constructions and combinationshereinafter described and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a transverse vertical section of an evener and swingle tree withour improved clevis arranged thereon, Fig. Q, is a rear elevation of aportion of the swingle tree and evener, showing the clevis in position,Fig. 3 is a front view of a portion of a swingle t-ree and evenershowing the clevis arranged thereon, Fig. 4 is an elevation of theclevis, Fig. 5 is a detail, perspective view of the plate, as arrangedto rest upon the surface of the evener.

In the drawing, 2 represents an evener and 3 a swingle treeLboth ofwhich may be of ordinary construction. The swingle tree is preferablymade light and small and this we can readily do without weakening thesame, owing to the fact that there is no bolt hole through the swingletree for the pivot bolt.

The main portion of the clevis consists of the strap 4, which passesaround` the swingle tree 3 and is provided with the downwardly extendingportion 16 that passes under the evener, as shown in Fig. l. This strapis preferably stamped from a single piece of sheet metal and is providedwith openings adapted to receive a screw bolt 5 carrying a nut 6, bymeans of which the strap may be clamped solidly to the swingle tree 3. Acentral hole 7 is provided in the strap 4 directly under the center ofthe swingle tree. A plate 8 -rests upon the top of the evener and isprovided with the downwardly turned end 9. This plate is shown in theperspective view in Fig. 5. It is provided with an opening l0 and apivot bolt 11 is passed through the central opening in the strap 4 andthe shoulder on the under side of the head of said bolt rests upon theplate 8, being countersunk in the horizontal or flat portion of thestrap 4. At its under side the swingle tree is provided with a washerplate 14, and the bolt 1l after passing through the evener and throughthe plate 14, is provided with a nut 15, by means of which the clevissurrounding the swingle tree 3, as well as the swingle tree and itspivot bolt 11 are compelled to remain properly connected and in properalinement. When it is desired to remove the swingle tree from the strap4, the bolt 5 is partially or wholly released and the swingle tree canthen be readily removed from said strap.

The advantages of the construction arise principally from the fact thatthere are no holes through the swingle tree, which may therefore, bemade small and light. The strap, which passes around the swingle tree,is preferably made by stamping from a single piece of sheet metal and itis connected to the pivot bolt, both by means of the head of said boltand also by having the threaded end pass through the opening in thelower part of said strap, the bolt being plied for securing a swingletree to anv evener, it will be understood that the clevis is applicablefor securing a swingle tree to the cross bar of a pair of buggy thills,or for securing an evener to its support.

We claim as our invention 1. The combination, with an evener and swingletree, of a clevis comprising a strap 4 extending around said swingletree and having a downwardly extending end that projects beneath theevener and `is provided with an opening in vertical alinement with thepivotal point of said swingle tree, the bolt 5 connecting the parts ofthe strap 4, a plate 8 arranged upon the top of said evener, and thebolt 11 extending through the strap t at the under side of the swingletree, through the plate 8 and the evener and through the free end of thestrap 4, substantially as described.

2. The Combination, with an evener and swingle tree, of a eleviscomprising a strap extending partially around the sWingle tree, said@levis having a loop formed therein, the upper portion of' said loopbeing near the free end of said strap, a holt passing through said freeend and through said loop and adapted to draw said strap snugly aroundthe swingle tree, the lower portion of said loop having an end extendingbaokl5 Wardly under the evener, and a pivot holt passing through thelower portion of said strap` and through said evener and the end of saidloop and pivotally connecting said swingle tree and evener together.

In Witness whereof, We have hereunto set our hands this 20th day ofAugust 1909.
